LONDON, Oct 30 (Reuters) - Thje price of copper rose on Monday, pulling away from the previous session's two-week low as a retreat in the dollar after its biggest one-week gain this year tempted buyers back to the metal.
Copper, chiefly used in construction, slid more than 2 percent on Friday to a low of $6,782.50, its weakest since Oct. 11.
"A large part of the move last week was due to strength in the dollar," ING analyst Warren Patterson said. "Now we're seeing a correction. The dollar is weaker, and you can see across the base metals complex that it's a little bit firmer today."
"Sentiment around the base metals is still fairly positive," he added. "On Friday we got some good GDP numbers out of the United States for the third quarter, and the stronger data does support a more robust demand side for the base metals market."
